> Workload management can defined Rules that are bound to a resource plan. Each rule can
have a trigger expression and an action associated with it. Trigger expressions are evaluated
at runtime after configurable check interval, based on which actions like killing a query,
moving a query to different pool etc. will get invoked. Simple rule could be something like
> {code}
> CREATE RULE slow_query IN resource_plan_name
> WHEN execution_time_ms > 10000
> MOVE TO slow_queue
> {code}
